PRESS FOR FRUIT, PULP, OR OTHER SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 429,238, dated June 3,1890.

Application filed August 16, 1889- Serial No. 320,962. (No model.)Patented in England May 21, 1889, No. 8,434.

To all whom it may concern: I

Be it known that I, RUPERT HEATON, a British subject, residing atMalaga, Spain, have invented certain new and useful Improvements inPresses for Fruit, Pulp, or other Substances, (for which I have appliedfor Letters Patent of Great Britain, No. 8,43%, dated May 21, 1889,) ofwhich the following is a specification.

The present invention refers to an improv ed press for pressing fruit,pulp, and other substances, and which is designed to resist a greatpressure.

In the accompanying drawings, Figure 1 is a vertical section of thepress, and Fig. 2 a horizontalsection of the same on theline as y ofFig. 1.

The apparatus consists, essentially, of two principal parts A and B,which are connected together by means of standards or columns C. Theupper part A forms a hydraulic cylinder and contains a piston D of largediameter.

On a suitable carriage H rests a basket or receptacle E, of a largerdiameter than the above-named piston D, and this receptacle may be ofiron or other suitable material, and is preferably constructed inseveral pieces, braced together by bands or hoops, and arranged in sucha manner that the receptacle can be easily opened to empty and clean theinterior. The walls are perforated bya great number of holes, and thebottom plate F is also perforated. This receptacle is provided with aninner lining of linen, cotton, or other suitable fabric J, which coversthe inn er walls and the bottom of the receptacle, and which must letthe juice of the fruit or the liquid of the pulp or the like passthrough it.

The operation is as follows: After the receptacle E is filled with thematerial to be pressed it is placed in the apparatus and covered with acover G, which may be fastened to it by means of bolts I, and throughwhich passes the piston of the above-named hydraulic cylinder. Taterunder pressure is then introduced in the hydraulic cylinder of thepiston D, which will be driven into the receptacle E, and thus press thematerial contained therein, the juice or liquid of which is forced andfiltered through the lining J and the holes of the receptacle. WVhen thematerial is suffieient-ly pressed, the water under pressure is cut offfrom above the piston D, and after the fastenings l have been loosenedwater under pressure,by means of the pipe L, is introduced into a secondsmaller hydraulic cylinder N, arranged above the first, the piston M ofwhich is mounted on the same rod 0 as the piston D, and thus the saidpiston D is lifted out of the receptacle E, which can now be emptied andrefilled for the next operation.

I claim- 1. In a press for fruit, pulp, &c., the combination, with thepress-box having the sides perforated from top to bottom and an openingin the top of less diameter than the internal diameter of the box, of aplunger fitting in said opening for expressing the juice, whereby aspace will be left all around the plunger for the pulp, substantially asdescribed.

2. In a press for fruit, pulp, &c., the combination, with the press-boxhaving the sides perforated from top to bottom, and a removable tophaving an opening therein of less diameter than the internal diameter ofthe box, of a plunger passing through said opening for expressing thejuice, whereby a space will be left all around the plunger for the pulp,substantially as described.

I11 testimony whereof I have hereto set my hand in the presence of thetwo subscribing witnesses.

RUPERT HEATON.
